-wave Charge- Superconductivity From Fluctuating Pair Density Waves
Yi-Ming Wu, Yuxuan Wang
We present a theory for charge- superconductivity as a leading low-temperature instability with a nontrivial -wave symmetry. We show that in several microscopic models for t…
Pair density wave order from electron repulsion
Yi-Ming Wu, P. A. Nosov, Aavishkar A. Patel +1
A pair density wave (PDW) is a superconductor whose order parameter is a periodic function of space, without an accompanying spatially-uniform component. Since PDWs are not the out…
Superconductivity out of a non-Fermi liquid. Free energy analysis
Shang-Shun Zhang, Yi-Ming Wu, Artem Abanov +1
In this paper, we present in-depth analysis of the condensation energy for a superconductor in a situation when superconductivity emerges out of a non-Fermi liquid due to pai…
Pair-density-wave and chiral superconductivity in twisted bilayer transition-metal-dichalcogenides
Yi-Ming Wu, Zhengzhi Wu, Hong Yao
We theoretically explore possible unconventional superconductivity induced by weak repulsive interactions in twisted bilayer TMD (e.g. WSe) in the presence of an out-of-plane e…
Interplay between superconductivity and non-Fermi liquid at a quantum-critical point in a metal. VI. The model and its phase diagram at
Shang-Shun Zhang, Yi-Ming Wu, Artem Abanov +1
In this paper, the sixth in series, we continue our analysis of the interplay between non-Fermi liquid and pairing in the effective low-energy model of fermions with singular dynam…
Interplay between superconductivity and non-Fermi liquid at a quantum-critical point in a metal: V. The model and its phase diagram. The case
Yi-Ming Wu, Shang-Shun Zhang, Artem Abanov +1
This paper is a continuation and a partial summary of our analysis of the pairing at a quantum-critical point (QCP) in a metal for a set of quantum-critical systems, whose low-ener…

Yi-Ming Wu, Shang-Shun Zhang, Artem Abanov +1
In this paper we continue our analysis of the interplay between the pairing and the non-Fermi liquid behavior in a metal for a set of quantum-critical (QC) systems with an effectiv…

In this paper we continue our analysis of the interplay between the pairing and the non-Fermi liquid behavior in a metal for a set of quantum-critical models with an effective dyna…
Interplay between superconductivity and non-Fermi liquid at a quantum critical point in a metal. II. The -model at a finite for
Yiming Wu, Artem Abanov, Yuxuan Wang +1
In this paper we continue the analysis of the interplay between non-Fermi liquid and superconductivity for quantum-critical systems, the low-energy physics of which is described by…
The interplay between superconductivity and non-Fermi liquid at a quantum-critical point in a metal
Andrey V. Chubukov, Artem Abanov, Yuxuan Wang +1
Near a quantum-critical point, a metal reveals two competing tendencies: destruction of fermionic coherence and attraction in one or more pairing channels. We analyze the competiti…
The special role of the first Matsubara frequency for superconductivity near a quantum-critical point -- the non-linear gap equation below and spectral properties in real frequencies
Yi-Ming Wu, Artem Abanov, Yuxuan Wang +1
Near a quantum-critical point in a metal a strong fermion-fermion interaction, mediated by a soft boson, destroys fermionic coherence and also gives rise to superconductivity. In a…
Superconductivity above a quantum critical point in a metal -- gap closing vs gap filling, Fermi arcs, and pseudogap behavior
Artem Abanov, Yi-Ming Wu, Yuxuan Wang +1
We consider a quantum-critical metal with interaction mediated by fluctuations of a critical order parameter. This interaction gives rise to two competing tendencies -- pairing and…
Multiple pairing states and temperature-dependent gap anisotropy for superconductivity near a nematic quantum-critical point
Avraham Klein, Yi-Ming Wu, Andrey Chubukov
Superconductivity in many strongly correlated materials appears in proximity to a density-wave or nematic order and is believed to be mediated by quantum-critical (QC) fluctuations…
Pairing in quantum-critical systems: , , and their ratio
Yi-Ming Wu, Artem Abanov, Andrey V. Chubukov
We compute the ratio of the pairing gap at and for a set of quantum-critical models in which the pairing interaction is mediated by a gapless boson with local susce…
